The majority was fine, the first 5 questions were pretty much standard M2. The last 3 questions came at stuff from a different angle - I can totally understand where the answer has come from looking at the mark scheme, but in the limited time available I just didn't 'click' as to how to do it.

That worries me. My M2 mock is 8th May. Is there any good way I can prepare?

I think doing at least one of the more recent papers beforehand (don't go crazy and do all of them though, save them for closer to the real thing). I'd also go through the paper with a highlighter and circle/draw attention to anything important beforehand (I didn't do this and I think it might have helped).

So for part bi the statement " the maximum length of the string in the subsequent motion is L" basically means that L is the sum of the extension and natural length. So where is the extension (I think you've got it as x) which means . Ok great we've got the extension in terms of now so that means we can use it in the EPE formula in place of the .

Using conservation of energy the Initial GPE = EPE + KE + Final GPE . If we consider the maximum height to be L then equation becomes Initial GPE = EPE (the KE disappears because the final velocity is zero at the maximum length of the string)

Tricky question since I've not done much recently . But it's definitely the hardest module out of the ones I'm doing (FP1, M1 and M2). Actually come to think of it, it's the hardest out of all the modules I've done (D1-2 and C1-4).
You've posted some good questions which keeps me on my toes. Keep them coming
